In the past week, perhaps following the most recent Zwift update (?), Zwift/Zwift Power has stopped recording and/or showing Stryd power numbers. This may be an unintended consequence of the update. A knock-on effect is that resulting .fit or .tcx files, that normally can be uploaded to the Stryd PowerCentre, are now being tagged as ‘not supported file format’. These file formats are normally supported by Stryd, however, this error message is likely the result of the files lacking power data.
It’s requested Zwift/Zwift Power return to including Stryd power numbers.
